Abstract

The invention relates to a system and a method for establishing a connection via an access network (30) in communication with at least one user terminal and at least one backbone network (100) comprising at least user terminal authentication and authorization means (50 ) and at least one user data processing node (60, 62), wherein the connection of the user terminal (10) to the access network (30) is authenticated, and at least one user data processing node is selected based on the selection information conveyed in the authentication signaling One of the processing nodes (60, 62). Then, the tunnel parameter information of the selected user data processing node is notified to the access network (30), and a tunnel is established between the access network (30) and the selected user data processing node (60) based on the tunnel parameter information connect. By establishing a tunnel connection based on network signaling related to the two endpoints of the tunnel, a tunnel connection can be established between two network elements that initially do not know each other. In this way, cellular packet switched services can be accessed on access networks that do not provide context activation procedures or corresponding control plane signaling functions.

Description

technical field

[0001] The present invention relates to a method and system for establishing a connection via an access network, such as a wireless local area network (WLAN), which communicates with at least one user terminal and at least one backbone network, such as a general packet radio service (GPRS ) network or Universal Mobile Telecommunications System (UMTS) network, and at least include user terminal authentication and authorization devices and at least one user data processing node. Background technique

[0002] The market for wireless communications has grown tremendously in recent years. Wireless technology has now reached or is able to reach almost every corner of the globe. With the enormous success of wireless telephony and messaging services, it is hardly surprising that wireless communications are beginning to be used in personal and business computing. No longer limited by wired network facilities, people will be able to access and share information on a ...
